Movable magnetic marker



Patented Sept. 27, 1932 PATENT OFFICE CLIF'1ON C. ALLES;OF LOS ANGELES, CALIIE'ORNIA MOVABLE ICAGNETIC MARKER Afiplik:atiozi mm NojVeinber 11, 1930. Serial m. 494,860.

This invention relates to improved movable magnetic markers, and has for one of its principal objects the provision of a series of markers which can be moved and placed at will upon a designated surface, the surface itself having inscriptions or insignia thereon which in conj unction with the markers form an intelligible visually presented device.

Another importantobject of the invention is to provide a series of movable r shiftable magnetic markers which when applied t0 a surface provided therefor and arranged in a desired or necessary sequence Will produce a sign, picture 0r the like.

Still another and further important 0bject of the invention is to provide in a means for musical instruction, a chart composed of a sheet 0f soft iron 0r the like, and having the necessary markings thereon to represent a musical stafi, and markers composed 0f magnets with other markings or insignia thereon 0r adapted t0 be attached thereto, whereby these markings can be arranged and -2 moved at Will over the surface 0f the chart so as to visually display various notes and other portions of a musical seale.

Other and still further important objects 0f the invention willbe apparent. fron1 the disclosures in the accompanying drawings and the following specification.

The invention in a pref'exred form, is shown in the drawing and is hereinafter more fully described.

In the drawing:

Figure 1 is a plan view 0f a portion of the soft iron musical scale of this invention, showing permanent insignia inscribed there- 0n and various movable markers applied thereto.

Figure 2 is a sectional view of a part of the scale, showing a marker mounted thereon.

Figure 3 is a bottom plan view 0f a marker.

Figure 4 is a side elevation of the display attachment, whicli is attached t0 the magnet to form a marker.

Figure 5 is a detail view 0f a portion of one of the movable musical note insignia, showing k means for mounting the same on the boar"d by a magnet.

Fi ure 6 illustrates another form of mark ing evice and fittings therein for mounting on a magnet.

Figure 7 is a perspective view of one of the preferred forms of magnets.

Figure 8 is a side elevation of a larger marker as adapted 150 be mounted in a magnet.

Figure 9 illustrates a slight modification of one 0f the magnets.

As shown in the drawing:

The reference numeral 10 indicates generally a sheet of soft iron 0r sirnilar metal capable of magnetic action. This is preferably fitted in a surrounding frame 0r the like 12, and as shown in Figure 2, is provided 0n each side with a coating 0f paint 0r the like 14, this coating including 01 being arlapted to have inscribed thereon a suitable series 0f notations 0r markings Which in this particu lar case comprises the stafi of a scale as il1ustrated atl6.

Various markings, comprising essentially permanent magnets which may be either 0f the open ring, closed ring, horseshoe, or other desired shape, and the closed ring type of 15 Which is as shown at 18 in Figure 7 are adapted t0 be used with the sheet 10. The preferred form 0f magnet includes integral Iugs 0r supp0rts 20, and a cap 22 is adapted 130 be mounted in 0r on the magnet, this mounting being preferably by means of a plu a; 24 adapted t0 be fitted or mounted inside the ring 18 which comprises the permanent artificial n'1agnet.

The outer face 0f the cap 22 may h:xve any sort of a mmking thereon. such as a letter 0 3 'thelike which may be used t0 designate various notes as best shown in Figure 1.

Other devices, such as those which ordinarily form part 0f the musical scale can'be applied t0 the chart by means of. these magnets, and thesedevices may be 0f any suitable material, and 1nade 0f any necessary 0r desired shape, as illustratecl in Figures l, 5, and 6 that in Figure 5 being shown with a, plurality 0f openings 0r slots berein 26 int0 which the legs 200f the magnet can be fittecl for mounting 011 thelvoard. Another modification is sl1own in Figure 6 whereby 0nly two holes 28 are provided throgh which two of th0 legs 015 'ih0 nmgnet am passed f01 a suitab1e mounting on the chart.

When the notes am lauge, a device such as that illustraced in Fignre 8 is provided, this including n plug 24 adapted t0 be fitted inside the rin 18 zmd the attached cap 30 which is larger than the cap 22 shown in Fignre 4, thereby accommodating insignia such as that illustrnted z1t 30 in Figure l.

Another nwdification of tne magnet is shown in Figure 9 Wherein a flat plate 32 is providad which has a hook 34 thereon, and into this 11001; nmy be removably supported any desired. insignia in the f01n1 0f a ticket 01 the 1ike.

It '(fl1 be evident ahnt herein is provided a cha1t, ha fing in comblnation therewith und adapted t0 be used therson, a nn1nber 0f movable markers which when placed in any desired position 011 the chart Will remain so supported and wnich furner may be shift-ed aronnd t0 US'UHCG various combinations b0tn so fr as indicia 011 the chart is c0ncerned, and also nith respscu "a0 various combinatlons 0f the markers themselves. The apparatns is applicable f01 a great nnn1ber 0f nses, am]. it may b0 used widely in fields other than that 01 forming 1nusical notations. F01 instance, it nmy be nsed in forming signs, the insercs c21rzying enire vvords 01 letters t0 be associated With auch 0ther and with portions 0f tne bnckgronnd as deslred. Again, the inserts themserves 1nay be used t0 i01m pic tures after -;he fashi0n 0f a cutup uzzle. Othr uses Will be apparent.

I 21111 aware that many changes nmy be made and nu1nerous deiails 0f construction varied through0nt 21 wicae range without depart-ing f10n1 the principles 0f this invention, and I, th01efore, d0 n0t pnrp0se limiting t-he patent granted he1e0n otherwise than as necessitated by the prion art.

I c1ain1 as m v invention:

l. A 1neans f01 assmbling visual indicia, comp1ising: a mckground 0f nmgnetic matsria1, and magnetic markers adapted t0 be applied t0 the background, together with means 011 the marke1s f01 applying various indicia thereto, said 1neans comprising removable caps, and plugs 011 the caps adapted 110 be fitted int0 openings in the magnetic markers.

2. A means 'f01 assembling visual indicia, comprising 2 bn0kground 0f magnetic materia1, and n1agnec markers adapted to be applied t0 the background, together with 1neans 011 the 1nmkers f01 applying various indicia thereto, said means comprising removable caps, und plngs 011 the caps adapted t0 be fitted int0 openings in the magnetic markers, together with 00V01 members 0n the caps, said c0ver members adapted f0r imprinting the1eon.

3. A means ior shiftably assembling visual indicia, comprising a solid unitary background of soft sheet iron, a plurality 0f permanently magnetized markers aclapted to be applied to the background, and a number 0f suitably inscribed interchnngeable caps, any one 0f which may be releasably supported 0n a marker.

4. A mea'ns for shiftably assembling visual indicia, comprising a. solid unitary background 0f soft sheet iron, a plurality 0f permanently magnetized markers adapted to be applied t0 the background, und a number of suitably inscribed interchangeable caps, any one of Whi'ch may be releasably supported on a 1na1ker, extending lugs integral with each marker and adapted 130 contact the background and an additional plurality of variously shaped flat perforated indicia adapted t0 be mounted 011 the lugs and suppo1ted 011 the background by the markers.

In testimony whereof I aflix my signature.
